I claim:-

In a'bearing structure the combination of a housin'ghaving separable base and cover portions and an oil reservoir in said base portion, aligned bearing supports in said housing between said base and cover portions, horizontal webs extending from the sides of said baseportion to said supports and separating said reservoir from the top of said housing, bearing sleeves seated in said supports, a channel in each support beneath the sleeve therein, a shaft journaled in said sleeves, an oil thrower on said shaft between said supports for transferring oil from said reservoir into the top of said housing, a horizontal channel in each web communicating with both of said first named channels for intercepting oil delivered from said thrower, and ports in said sleeves communicating with said channels through which said sleeves are maintained flooded with oil from said channels.
